Metallurgy
Compositional data of elemental metal and metal oxide percentages of any material culture objects, including metals, ores, slags, ceramics etc. Within the dicipline of compositional analysis there is little agreement on how to store meausrements below detection limit, some are pulished as zero, or NA, or NULL, BDL, or hyphen etc. Here we use NULL, which simply means below detection limits.
